Answer:
24 hours
Step-by-step explanation:
Hi,
The equation to represent this situation would be 45x + 720 = 1800
(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)
Now, solve for x.
45x + 720 = 1800
Subtract 720 on both sides...
45x = 1080
Divide by 45 on both sides...
x = 24
He worked 24 hours that week.
Hope this helps :)
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
1)
-----> For the interval (-∞,-1)
Note The value of x=-1 is a open circle ( is not included)
This is a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-2,0)
2)
----> For the interval [-1,1]
Note The value of x=-1 and x=1 are closed circle ( both values are included)
This is an absolute function open upward
The vertex is the point (0,1)
3)
-----> For the interval (1,∞)
Note The value of x=1 is a open circle ( is not included)
The value of f(x) is negative for all values of x
therefore

i think c might be the right answer
